Introduction To Fiber Optical Products

According to the difference of optical fiber transmission point modulus, fiber can be divided into two types, Single Mode Fiber（SMF）and Multi Mode Fiber(MMF).

Multi Mode Fiber adopts the light emitting diode (LED) as the light source, the transmission distance of 1000Mb/s optical fiber is 220m--550m. The price of multimode optical fiber and multi-mode optical fiber ports are relatively cheap, but the transmission distance is close, so it is used more frequently in vertical trunk subset, sometimes it is also used for horizontal subsystems or architectural subsystems.

Single Mode Fiber adopts the light emitting diode (LED) as the light source, the transmission distance of 1000Mb/s optical fiber is 550m--100km. Both single mode fiber and single mode fiber ports are expensive,but it can provide longer transmission distances and higher network bandwidth, it is usually used to connect between remote networks or buildings. Namely building group subsystem.

Common single-mode fiber specifications are 8 / 125um / 9 / 125um and 10/125um, common multi mode specifications are 50/125um (European standard) and 62.5/125um (American standard). By contrast, 62.5 / 125um optical fibers are popular with most users, and has gained a solid position in the world optical fiber market.
